When will the National VI emission standards be implemented nationwide? The details are as follows: 1. The National VI policy for light-duty vehicles will be implemented from July 1, 2020, and the National VI policy for heavy-duty diesel vehicles will be implemented from July 1, 2019. 2. "Limits and Measurement Methods for Emissions from Light-Duty Vehicles (China VI)" will be implemented from July 1, 2020, and "Limits and Measurement Methods for Emissions from Heavy-Duty Diesel Vehicles (China VI)" will be implemented from July 1, 2019. Additional information: The National VI motor vehicle pollutant emission standards consist of two parts: "Limits and Measurement Methods for Emissions from Light-Duty Vehicles" and "Limits and Measurement Methods for Emissions from Heavy-Duty Diesel Vehicles". These standards are formulated to implement the "Environmental Protection Law of the People's Republic of China" and the "Air Pollution Prevention and Control Law of the People's Republic of China", to prevent pollution of the environment by exhaust emissions from compression-ignition and gas-fueled spark-ignition engine vehicles, to protect the ecological environment, and to safeguard human health.

I recently looked into the China 6 emission standards, which were implemented nationwide in two phases: China 6a started in July 2020, requiring all newly produced light-duty vehicles to meet this standard. Then, China 6b was fully rolled out in July 2023, and now most new cars on the market comply with the China 6b standard. However, major cities like Beijing and Shanghai acted more urgently, implementing the stricter China 6b as early as 2019. Personally, I think this policy is quite necessary—it reduces tailpipe pollutants by nearly half, significantly improving air quality. If you're buying a used car, pay special attention to the emission standards, as cross-province transfers might cause issues. I recommend checking local vehicle management regulations in advance to avoid pitfalls.
